Engine, PowerTech Plus™ 9.0 L power ratings and specifications
PowerTech Plus 9.0 L engine

PowerTech Plus 9.0 L engine

All John Deere 8030 Series tractors feature the reliable and proven 9.0 L (548 cu. in.) engines. These air-to-air aftercooled engines deliver constant power over a wide range of rpm with a power bulge above rated power and excellent torque characteristics.  

 

Model and horsepower outputs are shown in the chart below. 

 

Other horsepower ratings are included for reference to competitor’s gross or engine only power ratings.  There are several ratings systems used by other brands.  John Deere uses the horsepower rating standard 97/68 EC, which is widely used in Europe for various regulations.

How is the “engine only” rated and maximum power determined?

 

John Deere engineering uses a precise procedure to measure engine only power levels.  The 97/68 EC standard is required in the European Union (EU) as an emission test, so there is some relation to the power a tractor has as a whole functioning unit.  However, the procedure requires only that a production engine and radiator are used on a dynamometer test.  

 

You can use the 97/68EC horsepower ratings in the above chart to compare to competitor claims of “engine only” power.

PTO torque rise and power bulge
 
Torque rise comparison - 8430/8520 Wheel Tractor

Torque rise comparison - 8430/8520 Wheel Tractor

All 8030 Series tractor engines have a constant horsepower range of 1500-2100 rpm with a PTO horsepower bulge up to 13 percent.

Engines provide PTO torque rise up to 43 percent. There are new performance characteristics of the 9.0 L engines that assure excellent performance in most any situation.   Key engine features such as the Variable Geometry Turbocharger (VGT) and the 4-valve head provide the ability to bring on new levels of the rate of torque rise and fuel economy.

PowerTech Plus engines reach peak torque quickly. In the chart you can see when compared with previous models, 8030 Series tractors reach peak torque at 1600 rpm vs.1400 rpm.  From rated speed to peak torque the 8430 engine drops only 500 rpm and the 8520 will have to loose 800 rpm to reach peak torque.  Dividing the rpm change, it shows that a 9.0 L engine will achieve peak torque at a 35% quicker rate than the models it replaces.

 

The operator of a 8030 Series wheel or track tractor is sure to notice the resulting tractor performance gains made with plenty of torque and overall power.  Improved load starting, pulling through tough spots or transporting will be appreciated.

This comparison chart also shows that a current owner of an 8520 would be satisfied with the 8430 model performance if there are no additional farming needs that require more power

Reduced fuel consumption
 
There are several new designs in all of the 8030 Series tractors that have made a favorable impact fuel economy.  All of these designs work together to provide a more efficient use of engine power resulting in less fuel consumption. The new features are as follows:
The PowerTech Plus 9.0 L engine features include 24-valve head (4 valves per cylinder), variable geometry turbocharger, and single injector control.
 
The Vari-Cool™ system components: the variable speed fan and hood design.
           
Hydraulic circuit changes add steering to the integrated hydraulic pump.  A new on-demand ground drive pump can provide backup oil flow for steering, if needed.  (Not included on tracks tractors as tracks use hydrostatic/mechanical steering systems.)
           
Reduction in oil windage controls used in the drivetrain and brake system.   (Not included on tracks tractors as maximum ground speed is lower.)
 
There is more detail on each of these new design features in other sections of this manual.
 
John Deere factory observed testing has shown that most customers will see between 2 and 5 % reduction in fuel usage when compared to an 8020 Series tractor. For this to be measured accurately, you must do the same work that was done previously with another tractor. When John Deere engineers make a comparison test, every effort is made to test tractors with the same load, ground speed, and environmental conditions.  Your results may vary from the 2 to 5% reduction.  Actual reduction in fuel usage will depend on how the tractor is operated. 
 
Additional reduction in fuel usage can also come from the IVT™ (Infinitely Variable Transmission). See the IVT section of this manual for more details.

  • When compared to the 8.1 L engine used in prior models, the cylinder bore is 2.5 mm (0.1-in.) larger and stroke is 7.5 mm (0.3-in.) longer.   The 9.0 L (548 cu. in.) has a bore of 118.4 mm (4.66-in.) and stroke of 136 mm (5.35-in.).
  • The engine design utilizes metric-sized components and hardware for ease of service and commonality with the remainder of the tractor.
Oil and coolant drain intervals
 

The large oil sump located in any front axle provides oil capacity for long, 250-hour change interval (375 hours when John Deere PLUS-50™ oil and a John Deere oil filter are used.)

 

There is special engine break-in oil used at the factory to assure proper seating of all components.  That oil should be changed after the first 100 hours of operation.

 

To further reduce maintenance requirements, long life coolant/antifreeze with coolant conditioner is used as the factory fill on all 8030 Series wheel and track tractors.  The first required change interval is at 3 years or 3000 hours.  If John Deere Cool-Gard™ is used as replacement fluid, intervals can be extended to 5 years or 5000 hours.  The only thing that is required on an annual basis for your cooling system is a simple test of coolant conditioner.
